The traditional stone houses of Ivana and Savidug on Sabtang Island, Batanes, built to withstand powerful typhoons using thick limestone walls and cogon grass roofs. These Ivatan heritage houses have stood for over 200 years and represent one of the most intact examples of indigenous architecture in the Philippines. Walking through the village feels like stepping back in time to a simpler era.
